Smileys? Not at Work

Do you assume that adding a smiley to work-related emails can help you make a positive first impression? A new study has found that a smiley is not regarded the same way as a smile, and can actually have a negative impact on the initial impression created in formal work-related emails. “While an actual smile has a positive impact on creating an initial impression, adding a smiley can harm the person who included it in their email,” explains Dr. Arik Cheshin, one of the authors of the study.

The Blue Light Emitted by Screens Damages Our Sleep

The short-wavelength blue light, emitted by the screens we watch, damages the duration, and even more so, the quality of our sleep. This is the conclusion of a new study undertaken by the University of Haifa and Assuta Sleep Clinic. The study also found that watching screens that emit red light does not cause damage, and sleep after exposure to it was similar to normal sleep. “The light emitted by most screens - computers, smartphones, and tablets – is blue light that damages the body’s cycles and our sleep,” explains Prof. Abraham Haim from the University of Haifa, one of the authors of the study. “The solution must be the use of the existing filters that prevent the emission of this light.”
